Not all supplements are created equal. And, that’s hardly news.
The market is flooded with brands making bold health claims, and collagen is no exception. As a wellness writer, I’ve tried my fair share, and I’m often skeptical that I’ll see any real long-term difference in my hair, skin or nails. But if there’s one formula that’s catching my attention, it’s Elysium’s Cofactor.
This isn’t your ordinary collagen supplement. Cofactor blends clinically backed Premium Collagen Peptides, Hyaluronic Acid, Vitamin C and 250 milligrams of NR to support NAD+ levels — the coenzyme that biohacking enthusiasts have linked to cellular health and longevity. And right now, during Amazon’s Spring Sale, Cofactor is marked-down 35% off.
According to Elysium, Cofactor works by supporting your body’s natural ability to repair and maintain collagen — so it’s not just for hair, nails, skin elasticity and hydration, but also for overall vitality. Translation: internal and external benefits.
Reviewers are seeing the results, with one calling it the best collagen supplement they’ve tried. And that was just after the first month of use.

“My skin feels noticeably more hydrated and has a healthy glow that wasn’t there before,” the reviewer shared, adding that they love that it combines collagen peptides with NAD+.
The unflavored powder blends easily into any cold liquid, and each pouch contains 28 daily servings for a full month of support. According to Elysium, consistent use can lead to enhanced skin hydration within weeks and smoother skin with fewer visible wrinkles over time. Some users report benefits even sooner.
“It feels like I’m supporting my skin and overall wellness at the cellular level,” they added. “After just a few weeks, I’ve also noticed my joints feel less stiff, especially in the mornings.”

Amazon’s Big Spring Sale is a marathon compared to the retailer’s shorter deal events. Shoppers can take advantage of seasonal discounts running from Wednesday, March 25 through Tuesday, March 31.
Do you have to be an Amazon Prime member to shop?
Unlike Prime Day in July, this event is open to everyone who shops on Amazon. However interested shoppers can grab a 30-day free trial to try Prime, and its many benefits with no strings attached, and gain access to exclusive deals, special “Prime” badges on select items and the added convenience of fast, free shipping.
What are the best deals?
From reporting on Amazon sales for years, we can tell you for certain that Big Spring Sale is the ideal period to stock up on household essentials, refill your skincare empties, save on the best vacuums to save your spring cleaning projects, and comb through the massive catalog of Amazon best-sellers.
